I’ve thought for a while that it would be nice if AAC devices had an option that allowed users to have a more subtle control over the vocal output of their device: such things as varying the pace and pitch of the utterance within the sentence.

I bought myself an iPad this weekend just gone, so today I put together a demo of the sort of interaction behavior I’d like to see. Obviously this particular control method is only applicable to users with a certain degree of motor control, but I think there are a few other ways of getting the same effect.

I’m interested in people’s comments, suggestions, and feedback. Ideally, of course, some if you will say ‘X already does this!’, which would be excellent news.
